NEW YORK--Former President Herbert Hoover, asserting that the nation is lacking in unity, warned tonight that the "least perilous road" for the United sates in the current crisis is to give all possible war materials to Britain--but without conveys.

"The solution," he said, is not for us to go to war but to give her (Britain) every tool that will really aid her regardless of our preparedness."

Hoover addressed the nation over a nationwide radio network. He said it was his duty to speak on the basis if experience obtained as former commander-in-chief of the armed forces and as a member of the nation's war council in the last war.
